Calculate bend angle sheet metal.

Bending angles greater than 90 degrees. The material thickness will be measured in decimal form not by the gauge number. A is the bending angle in the above equation so. Right angles are the most common feature found in most sheet metal fabrication.

Sheet metal bend allowance calculator determines the bend allowance amount of metal to be added to the total layout when forming sheet metal. Automatically calculate bend deduction bend allowance and k factor for sheet metal fabrication and forming. This type of angle can also be referred to as a square bend. Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated.

Online bend deduction calculator. You only have to insert interior angle flange lengths k factor inside radius and material thickness. Tonnage charts bend deduction bend allowance and other forming calculations and charts often refer to a 90 bend. A bend equal to 90.

And by having t and the sheet thickness t we can calculate the k factor as follow. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. The bend allowance describes the length of the neutral axis between the bend lines or in other words the arc length of the bend.

Most sheet metal materials will conform to the calculations. With this free online tool we quickly get the sheet metal bend deduction and therefore the sheet metal blank initial flat length from the finished part measurements. Precision sheet metal fabrication request a quote. Like previous scenarios let s start by calculating leg length 1.

Therefore the bend allowance added to the flange lengths is equal to the total flat length. Cells on the right will output the desired values. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance. To calculate the neutral axis distance from the inner face t we can subtract inside bend radius from r.

Bend angle a degrees thickness t inches inside bend radius r inches must be greater than 90 and less than 180 degrees. As this happens you gain a small amount of total length in your part.
